Evaluation of cluster combination functions for mixture of experts

摘要

The mixtures of experts (MoE) model provides the basis for building modular neural network solutions. In this work we are interested in methods for decomposing the input before forwarding to the MoE architecture. By doing so we are able to define the number of experts from the data itself. Specific schemes are shown to be appropriate for regression and classification problems, where each appear to have different preferences.
